Outside the towering city wall, it is already full of monsters, especially their vanguard troops, it turned out to be a group of rat monsters, rat monsters are casting spells, I don't know what spells they are casting, but I can feel that the pressure on Chang'an City from the other party is very huge.

"Why didn't they attack, but chose to besiege the city?" Meng Xianchen also jumped onto the city wall and said.

"Have you seen those rat demons, these rat demons seem to be proficient in demon magic, what spells are being used now, and I don't know what spells they are, but if they drag on, I'm afraid it's very bad for us." I said.

Here, the dragon king came to my side, and the dragon king said: "The tree demon of Xuantian Sect has passed through the ground, and is now in the city, and it seems to have brought a lot of news, my lord, do you want to go down first to find out about the military situation in the place?" ”

"The Dryad is coming?!"

I jumped off the city tower happily, surrounded by some dawn people, and Emperor Tang Taizong had already come out, with a lot of guards standing beside him.

But the army of the General's Mansion has now been controlled by the demon lord, and we are not sure what this demon lord will do next.

If we choose to resist desperately, I believe that the demon lord will not take any advantage, so the demon lord's move seems to be to use a bloodless way to encircle and annihilate us in Chang'an City.

"Elder Lin!" A small sapling bouncing and jumping in the crowd.

I immediately recognized that this was the clone of the camphor tree monster, not his body, but I could also understand that if it was his body, it would be impossible to come to Chang'an City in just half a month.

The little sapling is quite cute, and it is also surrounded by several female disciples.

I pushed through the crowd and said, "Camphor Dryad, did you find anything?" ”

"Through my spying, I discovered that the enemy is using the 'shrink into inches' spell!" The little sapling said.

"What do you mean?"

"Elder Lin, please look here!" The little sapling came to the side of a house, he pointed to the crack in the ground and said: "This house was originally two zhang wide, but now it has been shrunk, and now it is less than two zhang, and in this formation of the enemy, Chang'an City will eventually become a thread!" ”

"What line? Isn't it a city? I wondered.

After a small amount of explanation, I understood the meaning.

The basic principle of two-way foil is two-dimensional, the essence of which is to curl and compress a single dimension in the original three-dimensional space, and then realize the gradual devouring and dismantling of space, and most parts of the original three-dimensional space will no longer exist and become two-dimensional.

A typical dimensional strike in two-way foil science fiction, a dimensionality reduction attack weapon.

He took classical physics to the extreme. However, the two-way foil is a change of dimension, which uses the laws of the universe as a weapon to reduce the object from three dimensions to two dimensions, resulting in the loss of a large amount of energy and material information, and finally disappearing in the three-dimensional universe.

To put it simply, it is to flatten something, such as a person, and turn that person into a being as thin as a piece of drawing paper, which may be even thinner, and it is originally three-dimensional, but it immediately becomes flat.

And this shrinkage into inches is even more incredible, he not only made the entire Chang'an City two-dimensional, but also made Chang'an City unable to exist even on a plane, and then turned Chang'an City into a line perpendicular to the ground.

The little sapling jumped into the crowd and said, "That's it! ”

As he spoke, the little sapling grabbed a handful of soil, and then patted it: "Look, this clod of soil is Chang'an City, and it will be flattened by this formation, and then it will become a vertical line." ”

As he spoke, the little sapling twisted the soil into something the thickness of a hair: "When the entire formation is realized, everyone in Chang'an City will be trapped in such a thread!" ”

"Infinite compression." The Dragon King gritted his teeth and said, "This is no longer a spell that humans can recognize, this is simply a spell formation that breaks through the views of ordinary people!" ”

"That's why so many rat demons cast spells together, as long as the demon lord lets the formation be fully deployed, then we will have a radius of several miles, that is, the entire Chang'an City, will be compressed into something the thickness of a hair by this formation, and then everyone will have to die." I said.

"This news can't be spoken, let alone let Your Majesty know, now everyone hasn't realized that everything around us is being compressed, once everyone knows that we are trapped in the formation, I'm afraid there will be a huge mess." Tuxingsun said.

"Is there any other way to resolve this?" I looked at Feng Linfa, Feng Linfa was a master of formations, and the three brothers of their Feng family were all extremely good at formations.

Feng Linfa pondered for a moment, and suddenly opened his eyes.

The big guys also looked at him expectantly, and I hurriedly asked, "Is there a way?" ”

"No, even if we build a teleportation array, but the outside of the city are all demon clans, it is not easy for us to teleport out, and the entire Chang'an City has been locked, so we can't teleport out at all." Feng Linfa said.

"What if I use the earth escape that I'm good at?" At this time, Tuxingsun came over and said, "Before the collapse of Chang'an City, we will turn everyone underground, and then go from underground to the surface. ”

"As I said, Chang'an City is equivalent to a circle on a picture, and the other party's formation is to make the circle three-dimensional, isn't the three-dimensional circle a ball, the edge of the ball is locked, and we can't get out at all." Feng Linfa said.

I looked around and I said, "I have a solution." ”

Saying that, I drew several circles on the land, and I said: "Let Tuxingsun open an underground cave at the edge of the city, and then lay a teleportation formation on top of the underground cave, now we teleport without any meaning, but you think carefully, the enemy's spell can only compress things on the surface, but things underground, you look at the traces on the ground." ”

Everyone looked over, and I pointed to the compressed house, which had shrunk in size, but the land was still the same.

Feng Linfa looked at me excitedly: "Go on!" ”

"Everyone used to jump circles when they were kids, right? Let's say there are ten circles, and then everyone jumps from the first circle to ten circles, and we have to jump ten times along the way, and let's say this circle is our teleportation formation, we have to teleport ten times. ”

"And we put down the teleportation array in the underground cave placed at the edge of the city, because we can't get out of the city, so it is set up directly below the city, and then the city begins to compress, and when the compressed boundary reaches a certain level, after completely leaving the first formation cave, the people inside us will teleport to the outside formation, with this formation as a traction, it is equivalent to having an invisible jumping platform, so that I can wait to leave the compressed range."

I looked at Tu Xing Sun: "Before that, Tu Xing Sun was at the feet of the enemy, about a hundred meters underground, dug ten 'jumping formations' We use the teleportation of the formation to teleport the people inside underground, although they have to jump many times, but they can perfectly avoid the enemy's eyeline, although they have thousands of troops on the ground, but what is happening underground, they don't know!" ”

My explanation, although it was difficult to understand, Feng Linfa should have understood, and his excited body trembled: "Okay! It's a good idea! ”

Tuxing Sun Yi gritted his teeth: "Fight, although there are so many people, but if you don't fight, after they finish compressing us, everyone will have to die!" ”

Tuxingsun immediately began to carry the dirt, digging a cave in the ground, and the people on the ground also began to help carry the dirt.

Feng Linfa and the others began to draw the formation, because there were too many people, so we planned to use the wheel-type teleportation method.

To put it simply, it is to divide the people into more than a dozen teams, the first group of people goes in first, and then they start to teleport to the first cave, and when they teleport to the second cave, the second wave of people starts to teleport to the first cave.

Then the first group of people went to the third cave, and the third wave of people also began to teleport, so complicated.

As long as the danger of the "lock the land into inches" spell is lifted and the people are moved to a safe place, it will be a great advantage for us.
